background obstructive sleep apnea (osa) is a common sleep disease. it is associated not only with hypertension but also with other cardiac complications. thus, the early detection of cardiac disorders is very useful. objectives we sought to evaluate different echocardiographic parameters. patients and methods this cross-sectional study was done on 55 patients with osa. the patients were divide...

PURPOSE To investigate right ventricle function in successfully reperfused ST elevated myocardial infarction (STEMI) and to compare reperfusion strategies. METHODS From January 2007 to August 2008, 33 patients with anterior myocardial infarction (MI) and 48 patients with non-anterior myocardial infarction were enrolled in this study. Patients were treated with thrombolytic therapy (TT) or pri...

BACKGROUND The aim of our study was to evaluate in stable outpatients with systolic heart failure (HF) the 3 months effect of ivabradine on LV synchronization and Tei index in stable outpatients with systolic HF. METHODS We evaluated prospectively 40 (30 males, 10 females) patients with HF. All patients were evaluated before and after treatment by transthoracic M mode, two dimensional (2D), p...

OBJECTIVE To investigate the fetal right ventricular diastolic function under the condition of umbilical cord around neck (UCAN), and analyze the changes of the right ventricular propagation velocity (Vp), then discuss the clinical value of the color M-mode echocardiography in the evaluation of fetal ventricular diastolic function quantitatively. PATIENTS AND METHODS All patients enrolled wer...

BACKGROUND The right ventricular (RV) Tei index (TX) has a significant correlation with the severity of pulmonary hypertension. However, the role of RV dysfunction in dogs with myxomatous mitral valvular heart disease (MMVD) has not been addressed. OBJECTIVES To investigate the correlation between right ventricular Tei-index (RVTX) and the prognosis for dogs with MMVD. ANIMALS Thirty client...

AIM The aim of the study was to determine if the tissue Doppler imaging (TDI)-derived myocardial acceleration during isovolumic contraction (IVA) of tricuspid lateral annulus could be used in early detection of RV systolic dysfunction in patients with mitral stenosis (MS), before the clinical signs of systemic venous congestion occur. METHODS One hundred and twelve patients with rheumatic MS ...
